A majority of the wildlife parks, including the tiger reserves, are now closed, so August is not a good time for a wildlife safari. There are however, lots of natural and cultural wonders to be explored in India, so if you are not travelling for the wildlife, an August safari is possible, so long as you don’t mind rain, heat, and some vibrant thunderstorms.
Areas such as Ladakh are stunning at this time, with a more bearable climate. There are monasteries that few get to visit, so it is a great place if you want to see a different side to India.
Back towards more central India, you can still visit the Taj Mahal in Agra, explore the markets and shops of Old and New Delhi, or head to the holy city of Varanasi, where it is actually a prime month for cruising along the Ganges. The Ganges are incredibly sacred for Hindu’s, and a cruise is very spiritually rewarding, allowing you to access lots of places that can’t easily be discovered by road.
